Method and apparatus for changing connection state of terminal

The present embodiment relates to a control plane signaling method for decreasing signaling according to a change in the connection state of a terminal, and an apparatus therefor. More particularly, the present embodiment relates to a method and an apparatus for changing a connection state using a paging message by a terminal in a light connection state. An embodiment provides a method and apparatus for changing a connection state by a terminal, the method comprising steps of: receiving a radio resource control (RRC) message including indication information indicating state change into a light connection state from a base station; configuring the connection state of the terminal into the light connection state on the basis of the indication information; receiving a paging message for the terminal; and determining to change the connection state of the terminal on the basis of a terminal identification included in the paging message.
